The inequality that models all possible prices,p, in dollars, for a pair of pants that casey can afford is P ≤ 20
Given that, Casey has at most $50 to spend on pants.
She wants but 3 identical pairs of pants and has a $10 off coupon.
We have to find which inequality models all possible prices,p, in dollars, for a pair of pants that casey can afford
"p" represents the price in dollars for a pair of pants that casey can afford
Now, we know that,
Money spent casey ≤ $ 50
Cost of 3 identical pairs of pants – coupon worth ≤ 50
3 x cost of 1 pair of pant – 10 ≤ 50
3 x cost of 1 pair of pant ≤ 50 + 10
3 x cost of 1 pair of pant ≤ 60
Cost of 1 pair of pant ≤ 60/3
$ P ≤ 20
P ≤ 20
Hence, the inequality is P ≤ 20
